Every winter, Fred and Billly go deer hunting without success. Finally, they devise a foolproof plan. They will purchase a female deer costume and learn the mating call of a female deer; next winter, they will hide in the costume, lure a buck, then ditch the costume and shoot the deer.
Winter arrives, and the two men set themselves up on the edge of a clearing, don their costume and begin to give the deer love call. Before long, their call is answered as a huge buck comes crashing out of the forest and into the clearing. When the buck gets close enough, Fred says, “Okay, let’s get out and shoot him.”
After a long moment, Billy says, “This damn zipper is stuck! We’re trapped in here! What are we going to do?”
Fred replies, “Well, I’m going to start nibbling grass, but you’d better brace yourself.”
